Render tables from rtl_power to a nice heat map

rtl-gopow's Issues

Feature request: Generate Heatmaps from TinySA Ultra spectrum analyzer

The TinySA Ultra spectrum analyzer has the scan and scanraw commands that can be used similarly to rtl_power.exe to acquire data with which to generate a heatmap. Some details here.

It would be interesting to be able to generate a heatmap from TinySA Ultra, which by far offers the ability to analyze the spectrum well beyond the 1.7 GHz of an Rtl Sdr dongle, being able to go up to 6 GHz and even higher ...

GoPow for Windows 32 bit OS

Hello,

if possible please add a redy to run binary of GoPow for Windows 32 bit OS.

Thank you.

I can't build a binary

I suspect that I am making a silly mistake, any idea what I am doing wrong ?

I previously setup my environment with the following commands:
$ sudo apt-get -y install golang
$ export GOROOT=/usr/lib/go
$ export GOPATH=$HOME/go

$ go get github.com/Sirupsen/logrus
$ go get code.google.com/p/freetype-go/freetype
$ go get github.com/dustin/go-humanize
$ go get github.com/lucasb-eyer/go-colorful
$ go get github.com/codegangsta/cli

So new to go, as you might have guessed.

Feature request: Display pMax and pMin in image

Would it be possible to add the pMax and pMin values to the data in the bottom left of the image? It would also be nice to know if those values were the calculated values or the user supplied values.

Thanks.

Broken Binary - Linux release not working on Ubuntu 20.04

It's not working for me on Kubuntu 20.04 LTS, keeps saying: gopow: command not found as if the file didn't exist.

No options seem to work even if I give it the input file and output.

The only info I managed to get was when issuing a command "Open In Terminal":
DATA[0000] load failed error=missing input file

I'll try building and compiling myself later.

EDIT: Typo FATA fixed to DATA, not sure how that happened.

Navigate tool

Hi!
Can You advise some comfort way to navigate on pixel/frequencies? Now it is very difficult to count pixels from known markers.
Some tool with cursor and hint about current frequency under cursor?
Thank You.

Doesn't build on Ubuntu i386

Feature request: possibly support rtl_power_ffw?

I believe the performance of the program can be improved by using ffw and its more optimized code vs the standard rtl_power program

Problem with time ticks

Hi,

have a look at my rendered pictur , please. There's a problem with time ticks.

Thank you.

fatal error: runtime: out of memory

Hi,
running gopow with an extreme large file ( 21626847317 which equals 10 hours of 30 MHz scan) gives the out of memory error.

Anyway to solve this ?

Thanks,
Ben

Needs more documentation

What is the difference between rtl-gopow and heathmap.py?

Feature request: Vertical markers

Would it be possible to have gopow create vertical markers every X pixels? The purpose is to create a visual separation of bandwidth groups in a heatmaps.

The example below is a heatmap of 470MHz through 698M with 125k bins. In this example, inserting a vertical line every 48 pixels ( 125KHz * 48 = 6MHz for ATSC TV channels ) provides a great visualization of where each ATSC channel begins and ends.

Thanks.

I am impressed

With the plutosdr driver, scanning 60 MHz, for 3 hours, on a Raspberry Pi 4, gopow needs less then a minute to generate the heatmap output from the .csv file.

Very nice :-)

(Not really an issure, I know....)

Frequency scales discrepancy

Hello,

when scanning at the same time multiple frequencies intervals with a single rtl_power command like this

rtl_power -f 26M:43M:8k -f 70M:73M:8k -f 400M:460M:8k -f 900M:1370M:8k -g 0 -i 1 -e 2h 1.csv

GoPow cannot handle correctly the frequency scales, that instead of reflecting the scanned intervals, will show a contiguous scale.

For example, a 944 MHz signal, will be show on the 327 MHz range.

A fix will be much appreciated in the next planned release.

Thank You.

Difference when using concatenated data files vs concatenated images

I ran 5 x rtl_power scans for 10 minutes, each using a different gain (10, 20, 30, 40, 50)

for i in 10 20 30 40 50
do rtl_power -f 566M:608M:5k -e 10m -g $i -p 60 -i 1 -D 0 output-$i.log
done

Test 1: Process each file with gopow, ending up with 5 images. Use imagemagick to append the images into a single image.

Results: It looks like some sort of gain normalization routine is used, which results in 5 very similar looking images.

Test 2: Concatenate the 5 rtl_power data files into 1 large file and process the log file with gopow

Results: More of what I was expecting, with each scan getting more noisy as the gain is increased.

Feature request: Add support for frequency offset

This is an awesome tool, thanks for that!

One thing that is missing that exists in the heatmap.py is the possibility to set the offset for upverters that lot of people are using. So it would be really handy if you could just do -offset -120000000 and it would reduce that amount from the frequency in the CSV.
